TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5338 SUBJECT: GRB 060717: Swift XRT refined analysis DATE: 06/07/18 18:47:17 GMT FROM: Milvia Capalbi at ISAC/ASDC M. Capalbi, M. Perri (ASDC), D.N. Burrows (PSU), T. Sakamoto (NASA/ORAU) report on behalf of the Swift XRT team: We have analysed the first 8 orbits of XRT data from GRB 060717 (Sakamoto et al., GCN 5326). A Photon Counting mode image (11 ks) provides a refined XRT position: RA(J2000) = 11h 23m 21.79s Dec(J2000) = +28d 57m 03.3s with an uncertainty of 4.5 arcsec (90% containment). This position is 0.7 arcsec away from the XRT position quoted in Capalbi et al. (GCN 5331). The 0.3-10 keV X-ray light curve shows a power law decline with a decay index of -0.9 ± 0.2. There are only 56 counts, insufficient for spectral analysis. Assuming a photon index of 2.0 and the Galactic value for the column density (1.4e20 cm^-2), the estimated unabsorbed source flux at T+24h is about 3e-14 erg cm^-2 s^-1. This circular is an official product of the Swift XRT Team.
